Hui Wen Han commented on MAHOUT-358:
------------------------------------
here is the question from test.
1) the value has negative in
https://issues.apache.org/jira/secure/attachment/12441008/20100407_steer_item_out_part-00000
2) the recommendation count in the output file exceeds the expected count
sometimes
I want 10 recommendations, the file
https://issues.apache.org/jira/secure/attachment/12441008/20100407_steer_item_out_part-00000
,it's more sometimes
3) it seems that it not take the max N items some times, you can see in the
log file
4) the log seems right ,but the final output file is wrong (negative and count)
5) when use Text as output class ,there is no negative ,the recommendation
count also is right.
UserID is ok now .
